In this study, we try to extend our hypothesis, i.e., Normalized Visual Percept (NVP), to twilight (mesoscopic) vision. The key idea of the confirmation process is to focus on the visual perception of full moon textures. The main result suggests that the dynamic range at night is significantly wider than the daytime equivalent, i.e., CR (contrast ratio) was more than 106:1 vs. 104:1.
